Data Sheet
Hybrid Wire Grid Polarizer & Thin Film Dichroic Filter
Bookham and Moxtek, Inc. have collaborated to
produce a hybrid Optical Wire Grid Polarizer and
Thin Film Dichroic Filter combined on a common
glass substrate and specifically designed for
projection devices.
The Bookham AED coating technology produces dichroic
filters with industry leading performance and quality.
Combined with Moxtek’s best in class ProFluxTM wire grid
polarizers, the hybrid dichroic/polarizer provides an
unbeatable combination of price and performance.

Product Features:
• The Polarizer and Dichroic Filter combination will
replace each of the two separate elements in a
standard system
• Improved optical efficiency with less optical surfaces
• Reduces the cost of an extra optical component and
manufacturing assembly process
ProFluxTM polarizers are superior to all
other normal incidence polarizers
• Operate without degradation at high heat and
light levels.
ProFluxTM polarizers are recommended for use as
prepolarizers and analyzers and in polarization recovery
products with incident angles less than 20º. They may be
ordered in any rectangular size from 10mm x 10mm to
90mm x 90mm. Smaller sizes, other shapes (such as circles
and triangles) are available as special orders.
• Operate at acceptance angles of ± 20º without
depolarization of the skew rays and without
compensation films.
• Operate without degradation in typical consumer
display environments.
In order to provide optimum application performance,
ProFluxTM polarizers are available with various combinations
of high contrast and high transmission.
• Operate in combination with ProFluxTM beam
splitters enabling system contrast of >10,000:1

Off-Axis Performance
with angle of incidence, resulting in uniform system
performance over the aperture. This is illustrated in the
typical off-axis 1/2 angle performance graphs of
transmittance and contrast shown below.
The light entering a polarizer is typically a cone. The size
of the cone depends upon the f/number of the system.
Most systems us a cone half angle of less than 20º.
The ProFluxTM polarizer performance changes very little
